I have written a plugin that alters the assigned profile for an image however if a Proof Color preview has been done previous to my plugin's operations the preview will be incorrect. What I need to do is to read the settings from the View->Proof Setup->Custom...->Customize Proof Condition Dialog and reapply them afterwards. I'm having particular problems with the "Simulate Paper Color" and "Simulate Black Ink".
Many thanks for any help you can give me.
What do you have so far if I may ask?
